key to motion: A second‐generation molecularrotary motor, which contains a DB24C8 macrocycle ring incorporated into the lower stator half and a dialkyl ammonium ion attached to the upper rotor half, forms a [1]pseudorotaxane in less polar solvents such as CH2Cl2. In this self‐complexing system, acid–base‐controlled threading–dethreading movements can be utilized to unlock or lock the molecular motor
